Description

When generating with the attached schema where a query parameter is referencing an object, the called url doesn't explode the parameters despite me specifying it to do so.

openapi-generator version

5.3.0

OpenAPI declaration file content or url

Open API spec example

Generation Details

openapi-generator-cli generate -g csharp-netcore

Steps to reproduce

Generate classes using the provdied schema. I expected the calling url to be https://localhost/users/?limit=10&skip=0, but it's something in the line of https://localhost/users/?ListQueryParams=class ListQueryParams {%0a Limit%3a 0%0a Skip%3a 0%0a }%0a

Start with the OpenAPI schema in the linked gist and run the documented csharp-netcore generation command against it. Inspect the generated client request for the object-valued query parameter and compare it with the expected exploded URL; done means the generated call uses separate limit and skip query parameters instead of serializing the object.
